In September, the airline announced plans to make the international terminal at Hartsfield-Jackson into a biometric terminal, including facial recognition at check-in, at the security checkpoint, at gates and at Customs.

During boarding, the use of facial recognition saves an average of two seconds per passenger, or a total of nine minutes for boarding of a wide-body plane, according to Delta.

The Detroit News reported that the airline plans to expand facial recognition to the international terminal in the Detroit Metropolitan Airport by mid-December. It will then roll out facial recognition throughout that airport in 2019.
